IMPROVEMENT IN KNFi.IIII'G--lVlACLIEITIN'IEiSl The Schedule referred toin these Letters Patent and making part of the sarde.

To all whom it may conce/rn l Be it -known that I, FRANK BURNS, of Upper Gilmanton, in the county of Belknap, and State of New Hampshire, have invented an Improvement in Knitting-Machines; and l do hereby declare that the following is a full and exact description thereof', reference being had to the accompanying drawings, ymaking part of this specicationf- Y v Y Figure 1 being a top i/iew ot a cylinder' knittingmachine, provided with my improvement, enough of the machine being represented to show the application of the invention.

Figure 2, a-side' elevation of the same.

Like letters desigrgte corresponding parts in both figures.

Let A represent the needle-cylinderof the machine, bearing the needlesa a.;

B, the clearing-wheel, or its equivalent;

C, the loop-wheel; and

D, the yarn-earlier.K i

The nature of my invention consists in what Iterni 'a needle-protector, E, applied in connection with the loop-wheel C, in such a'manner as to prevent loose or tangled yarn from getting into the barbs of the needles in passing the said loop-wheel.

When the machine is doing good work, the' clearing-wheel B brings all the loops down from the barbs ofthe needles, and the work keeps down till it passes the 'loop-wheel G, and nothiug'more is needed. But if there is any loose or tangled yarn hanging outside i of the needles, as is frequently the case, theelearingwheel fails to bring and keep it down out ofthe barbs 0f the needles, and when the leaves of the loop-wheel seize it, it is carried up and tangled in the barbs of the needles, doing great damage thereto, sometimes even destroying the whole set at once, as the .entanglementincreases when once begun.

My needle-protector E completely obviates this i diihculty. It consists of a curved plate, 'attached at one end to the pivoter stud, b, of the clearing-wheel, and continues curving downward, thence below the Deedlefbarbs and under the .loon-wheel.. 0,. parallel..

with and a little distance from the needle-cylinder, substai'itially as represented. rlfhis downward curvature is suflicient to force down and keep below the loop-wheel all tangled or loose yarn, aner once getting below its upper end, where the clearing-wheel always delivers it; v

Thus, with this simple plate, which does not interfere with the action of the machine, except when bad work begins, a machine 'may be run, and use or destroy not more than twenty-five needles a day, whereas, without it,.from one hundred to oneA hundred and twenty-five needles are ordinarily required each day.

Its value and importance for this kind of knittingmachine are obvious. i l

What I claim as my'inventou, and desire to secure by Letters Patent, is y Y The needle-protector E, formed and arranged' 'upon a knitting-machine, substantially as and for the,

purpose herein specified.
